Thanks to my brother and my wife for making me aware of this 2009 New York magazine interview with Michael Caine. Here’s a great snippet.
Right after I got there, I was staying in the Beverly Hills Hotel. I saw John Wayne in the lobby, and I was gawking at him. He said, “What’s your name?” He’d just seen Alfie. Wayne became a friend. He gave me advice, like: “Talk low, talk slow, and don’t say too fucking much,” and “Never wear suede shoes, because one day, Michael, you’ll be taking a piss, and the guy next to you will recognize you, and he’ll turn toward you and say, ‘Michael Caine!’ and piss all over your shoes.” I couldn’t make this shit up.
